Inventor: SHEU SIMON
IPC: B21B28/02
Filed: 1991-05-06
Abstract: A method of rolling metal in a plurality of rolling stands with each of the stands having two or more rolls. The method includes first polishing the surfaces of the rolls to an average roughness of less than 0.3 microns, after which the roll surfaces are textured with a plurality of minute micron size craters. The roll surface and craters are then coated with a dense, hard material before the rolls are lubricated and used to reduce the thickness of the metal in the stands. To this end, the metal is directed through the stands, the craters being capable of retaining and carrying lubricant into the bites of the rolls without substantial adherence of metal to the roll surfaces and without substantial generation of wear debris on the surfaces of the rolls and rolled material.

IPC: G01F1/88
Filed: 1992-11-02
Abstract: The present invention is a method and apparatus for monitoring in real time the mass and energy flow rate of a gas through a pipeline. The invention determines the ratio of the mass flow rate of pipeline gas flowing through a pipeline compared to the mass flow rate of sample gas tapped from the pipeline line. The invention involves tapping sample gas from the pipeline and flowing the sample gas to a capillary tube or a similar device for creating a pressure differential in a small flow. The sample gas is maintained at substantially the same temperature as the gas in the pipeline while the sample gas is in the capillary tube. The sample gas flows through the capillary tube continuously as controlled by a flow controller at a rate that is independent of the pipeline gas flow rate. A differential pressure cell measures the pressure differential of the sample gas across the capillary tube and also measures the pressure differential of the pipeline gas across an orifice in the pipeline. The mass flow ratio of the pipeline gas flowing through the pipeline to the sample gas flowing through the capillary tube is computed using the pressure differentials measured by the differential pressure cell. 
     The energy content of the pipeline gas is determined by measuring the energy content of the sample gas and relating that value to the mass flow ratio of the pipeline gas compared to the sample gas. If the sample gas is a saturated hydrocarbon and is burned with air at maximum flame temperature, the energy content of the pipeline gas stream is mathematically related to the mass flow rate of the air and the mass flow ratio of the pipeline gas compared to the sample gas.

Abstract: The invention relates to a method of production of an annular or arc-shaped metal part. With the method according to the invention, relatively large metal parts with a high degree of stability and low weight can be produced by bending a sheet into a ring (100) and joining the ends of the sheet together, by stamping peripheral elevations and depressions (105, 106) in the sheet-metal ring thus formed by means of rolls (131..136) arranged inside and outside the sheet metal, the cooperating profiles of which rolls are adapted to the elevations and depressions to be produced, and by moving the rolls simultaneously in the radial direction and parallel to the axis of the sheet-metal ring during the stamping operation, so that the sheet-metal ring is stretched or compressed only in the radial direction. <IMAGE>

Abstract: A commutator has a central support (20,6,21) supporting a plurality of conductive segments (5) separated by a plurality of insulative segments (4). In addition to providing an insulative function between the conductive segments, the dielectric constant, the area, and the thickness of the insulative segments (4) are chosen so that they provide a capacitive effect, which capacitive effect suppresses current peaks during operation of the commutator. Preferably, the dielectric constant is greater than 10. The central support (20,6,21) may include a metal shaft (21) and an insulating ring (6), which insulating ring(6) is preferably of material with a lower dielectric constant thereby to suppress shorting between the shaft (21) and the conductive segments (5). It is particularly advantageous if the conductive (5) and insulative (4) segments are of ceramics material since this provides good wear resistance. In further alternatives, capacitors are formed between the conductive segments by rings (9) or other bodies (10) of insulative materials of a suitably high dielectric constant.

Abstract: A quantization parameter for use in encoding a region of an image is developed from a) a categorization of the region into one of a predetermined plurality of perceptual noise sensitivity (PNS) classes, b) a level of psycho-visual quality that can be achieved for the encoded version of the image, the level being selected from among a plurality of predetermined levels, and c) a prestored empirically derived model of the relationship between the PNS classes, the psycho-visual quality levels and the values of the quantization parameter. PNS indicates the amount of noise that would be tolerable to a viewer of the region, i.e., the perceptual sensitivity of the region to noise. Some characteristics on which PNS classes may be based are : spatial activity, speed of motion, brightness of the region, importance of the region in a particular context, the presence of edges within the region and the texture of the region, e.g., from "flat" to "highly textured". PNS classes that include combinations of the characteristics of a region of the image may also be defined. The PNS classes employed are selected by the implementor and may be determined empirically. The psycho-visual quality of an encoded image is the quality, as perceived by a viewer, of the version of the image that is reconstructed from the encoded image. It is determined from the complexity of the image and the bit-rate available to encode the image.

Abstract: A data processing system (3) generates successive individual numbers and write and read orders respectively for transmitting data variables from the data processing system to a memory device (1), and vice versa, via a variable register (9) in which data variables are temporarily stored. A pointer device (2) connected to the memory device converts the individual numbers to memory pointer values, so as to provide access to storage locations (10) indicated thereby, these storage locations being assigned to individuals identified by the individual numbers. For reading variables stored in the memory device, a time saving facility is obtained by providing the variable register with an activating input (18), and by including an intermediate register (13), a comparator (14), a control signal generator (15) and a stop circuit (7). A first individual number is temporarily stored in the intermediate register. The comparator compares the first individual number with a second individual number obtained from the data processing system immediately after the first individual number. The control signal generator generates a control signal when the comparison shows equality and when the second individual number belongs to a read order. The stop circuit responds to the control signal, by stopping the calculation of the pointer value belonging to the second individual number. The activating input of the variable register responds to the control signal by activating transmission of the temporarily stored data variable to the data processing system.

Abstract: The speed gradient (in the form of a segmental time gradient 2) is derived from the engine speed n of a motor vehicle. Drive train vibrations are detected by analysing this gradient 2. If it falls below a lower limit 3, the ignition angle is retarded, for example by switching from a set of basic ignition characteristics to a second set of ignition characteristics, thereby producing a reduction in the engine torque. Should the speed gradient exceed an upper limit 4, the ignition angle is advanced again or a return made to the basic set of characteristics. The upper and lower limits are dependent on the engine speed, as are the sizes of the ignition angle variations. <IMAGE>
